Optimize for Performance

In my career, I've seen countless developers fall into the trap of optimizing for performance too early.

Don't!

Don't optimize upfront unless you can see AND measure real performance issues.

Instead:

1. Make it work — focus on functionality, and surround it with tests.
2. Make it right — improve readability and maintainability.
3. If (and only if) performance issues arise:
   • Measure
   • Optimize
   • Repeat as needed

Premature optimization isn't just wasted time—it can make your code harder to understand and maintain.

Always remember: The cost of code is in the reading!
